Abstract:

Currently, different Earth-observation resources are usually managed by different organization sub-planners which lack interactions and cooperation among each other. Such independent resource operations are no longer efficient to meet diverse and vast observation requests, especially in emergencies, such as earthquakes, flooding and forest fire disasters. This paper addresses the issue of the coordinated planning of heterogeneous observation platforms, including satellite, airship and unmanned aerial vehicle(UAV). First, an agent-based coordinated planning architecture is proposed to integrate heterogeneous observation resources into a distributed and loosely-coupled earth-observation system. Second, the coordinated task planning problem is transformed into a problem of the task assignment among sub-planners. Third, a simulated annealing algorithm combined with a tabu list(SA-TL) is proposed to solve the task assignment problem. SA-TL is integrated with a tabu-list strategy, which improves the performance efficiently. Experiments and comparative studies demonstrate the superiority of agent-based architecture and the efficiency of SA-TL.
